Application July 9, 1931, Serial No. 549,757

. Renewed September 20, 1933 l 2 Claims.

This invention relates to an irrigating instrument for irrigation of theurethral canal and bladder and can also be used for the rectum, thegeneral object of the invention being to provide means whereby the fluidcan be readily introduced into the'canal or passage, and held thereinfor any desired length of time, after which by releasing the valve, thefluid will be discharged without removing the nozzle, so that the canalmay be irrigated as many times as desired, without removing the devicein order to discharge the fluid.

This invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the several views, and in which:-

Figure 1 is an elevation of the device.

Fig. 2 is an edge view.

Fig. 3 is a section on line 3-3 of Fig. 2.

Fig. 4 is a section on line 44 of Fig. 3.

Fig. 5 is a section on line 55 of Fig. 3.

Fig. 6 is a section on line 6-6 of Fig.

In these views, the numeral 1 indicates the body of the device which ispreferably of the shape shown, and said body has at one end the shield 2which is of concavo-convex shape and V having an opening therein throughwhich passes the nozzle 3, which is threaded in the body 1 and may havea slip joint therein. If desired, the shield can be formed with thenozzle, but detachably connected therewith.

A second nozzle 4 passes through the first nozzle as shown, and saidnozzle 4 is also detachably connected with the body and is incommunication with the inlet passage 5 which passes through the body andis adapted to be connected by a hose 6 to a container which may beelevated in order to cause the fluid to flow through the device bygravity.

The nozzle 3 is in communication with an outlet passage '7 and whichalso passes through the body and its outer end is in communication witha hose 8 which leads the discharging fluid to a basin or otherreceptacle. These two passages are intersected by a transverselyarranged cylinder 9 formed in the body and extends through one endthereof, and a piston valve 10 is slidably arranged in the cylinder andhas a groove 11 thereinfor registering with either passage.

' A spring 12 at the stem of the valve normally holds the valve with itsgroove registering with the discharge passage 7, but when the valve ispushed inwardly, this groove 11 will register with the passage 5 so thatthe fluid from the container will pass through said passage 5 throughthe inner nozzle 4 and thus enter the canal of the body through whichthe nozzle assembly is placed.

When it is desired to discharge the fluid, the valve is released so thatthe spring will return it to the position shown in Fig. 3, so that theinlet passage will be cut off and the outlet passage opened so that thefluid will pass into the canal through the passage 7 into the receptaclethrough which the hose leads. A packing gland 13 closes the outer end ofthe cylinder and the valve stem passes through said gland.

A vent 14 is formed in the body and opens into the inner cylinder toprevent pressure returning this end of the cylinder to interfere withthe inward movement of the valve. A substantially conical guard 15 ofwire or the like is formed at the outer end of the nozzle assembly asshown. It will of course be understood that the nozzle parts 3 and 4 maybe formed inwardly or separately as desired.

From the foregoing it will be seen that the device is in position andthe valve 10 pushed inwardly, fluid will pass from its container towhich the hose is connected, through the passage 5 and the nozzle 4 intothe canal of the body and as soon as sufficient fluid has entered thecanal, the valve is released and moved to the position shown inf Fig. 3so that the fluid can escape through the passage '7.

Of course, by holding the valve in its intermediate position, the fluidcan be retained in the passage.

As before stated, this device will permit the canal to be irrigatedseveral times without removing the device which is often painful andinjurious, and it permits effective ballooning of the valve so thatevery part of the walls of the canal is disposed to the influence of thesolution. The device also eliminates splashing of the solution on theoutside and no parts of the solution is visible from the time it leavesthe container until it comes out of the exit of the instrument. There isa complete control of pressure and every drop of the solution is appliedto the diseased tissues or membranes.

It is thought from the foregoing description that the advantages andnovel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction andin the combination and arrangement of the several parts, provided thatsuch changes fall within the scope of the appended claims.

Having thus described my invention, what I claim as new is:

1. An irrigator of the class described comprising an elongated solidbody having an enlarged central portion gradually decreasing in sizetothe ends thereof and said body having a recess in one end thereof andprovided with longitudinally extending inlet and discharge passagesopening out into the recess, a nozzle member composed of inner and outerparts fitting in the recess with the inner part in communication withthe inlet passage and the outer part in communication with the dischargepassage, said body having a transverse passage therein intersecting theinlet and discharge passages, a piston movably arranged in the lateralpassage and'having a groove therein, which in one position of the pistonwill be in alinement with one of the longitudinal passages, with a partof the piston closing the other passage, and in another position of thepiston, the groove will be in alinement with said other longitudinalpassage with a part of the piston closing the first passage, means foroperating the piston, and a shield connected with the nozzle end of thebody.

2. An irrigator of the class described comprising an elongated bodyhaving a relatively large threaded recess in one end'thereof with athreaded smaller recess in the bottom of the first-mentioned recess andsaid body having a longitudinally extending inlet passage passingtherethru with one end opening out into the small recess, said body alsohaving a longitudinally extending outlet passage therein having one endopening out into the large recess, an inner nozzle member threaded intothe small recess and receiving the liquid from the inlet passage, anouter nozzle member threaded in the large recess and discharging intothe outlet passage, the inner nozzle member having its outer endextending beyond the outer end of the outer member, and a disk connectedwith the nozzleend of the body and thru which the nozzle members pass.
